Definitions

  • the invention relates to a discharge device for contained in a container flowable and / or flowable bulk material such as cement or coal dust, which is attached to a lower discharge opening of the container and comprises a rotary valve.
  • the rotary feeder can consist of different types:
  • the bulk material can be offset laterally, for example tangentially, via the inlet of the feeder, radially or axially with respect to its axis, as in the document EP 1031014 B1 shown.
  • the bucket rotates in a vertical plane, in the second case in a horizontal plane. If the removal opening provided in the bottom plate of a cylindrical outlet part of the container, a laterally offset axial feed of the bulk material is recommended, because then the housing of the cell wheel can connect seamlessly to the outlet part with a minimum height.
  • a rotor driven in rotation about the axis of the outlet part is provided in the container near the removal opening, which mixes and loosens the bulk material before it is removed.
  • the removal opening is then often substantially smaller than the lateral extent of the base plate.
  • the maximum discharge capacity that is to say the quantity of bulk material removed from the container per unit of time, depends on the one hand on the properties of the bulk material and on the other hand on apparatus with a predetermined discharge opening and housing dimensioning essentially on the rotational speed of the cell wheel. Since the greatest speed is limited by design, the discharge capacity of the discharge devices of the type mentioned can not be significantly increased.
  • the invention is therefore based on the object to increase the discharge of a discharge.
  • all rotary valves may be of the same type and dimension. This possibility has especially for retrofitting already existing, equipped with a rotary valve discharge devices meaning, because this embodiment of the invention leads to no change in the height and the installation position. In the context of the invention, however, it is also possible to use rotary valves of different construction.
  • a horizontally rotating rotor is arranged in the outlet part above the bottom plate, which loosens the bulk material and conveys into the removal openings.
  • a manually operable or motor-operated gate valve is provided from the outside of the outlet part, which allows the shutting off or releasing one or more discharge openings or enemas.
  • Figure 1 shows first the lower, conically widening down part 10 of a container, otherwise not shown, which is filled in operation with coal dust or cement or raw meal or the like flowable bulk material.
  • a central, vertical shaft 12 On a central, vertical shaft 12, at least one double-wing loosening stirrer 14 is mounted within the part 10, the terminal, upright sheets 16, 18 strike along the inner surface 11 of the part 10 upon rotation of the Auflotechnischsrrockers 14.
  • the part 10 is sealingly attached to a circular discharge device, designated as a whole by 1, which has the same lateral extent as the part 10 on the annular flange 13.
  • An essential part of the discharge 1 is a rotary valve 5, the annular chamber 4 is open by an inlet port 3 for the bulk material in its lid 6 in part 10, and through an outlet 7 for the bulk material in its bottom 8 to a discharge chute 9, wherein the Outlet opening 7 is offset to the inlet opening 3 in the circumferential direction by about 180 °.
  • the shaft 12 extends to drive the Loosening stirrer 14.
  • drive elements such as gears for the rotary drive not shown in detail Zellenraderiel parallel to the shaft 12 within the annular chamber 4.
  • the drive elements are about a shaft 12 surrounding sleeve 15 and further, rotation transmitting elements with a motor 17 in driving connection. According to Figure 1, the motor 17 is arranged laterally standing next to the rotary feeder, while the drive motor 19 for the shaft 12 is located centrally below the rotary feeder 5 ( Figure 2).
  • the graph of Figure 3 illustrates that the inlet opening 3 has an oval shape and only about one half of the lid 6 makes, wherein the longitudinal direction of the inlet opening 3 has approximately in the direction of rotation of another four-bladed stirrer 21.
  • the four wings forming the stirrer 21 are attached crosswise to the shaft 12 just above the lid 6, so that the rotating stirrer 21 conveys bulk material lying on the lid 6 and loosened by it through the inlet opening 3 into the rotary valve 5.
  • the rotary valve 5 is concentrically fixed to the container part 10 in axial alignment with the shaft 12 (FIGS. 1, 2).
  • Figure 4 shows an embodiment in which the container part 30 and attached to the shaft 32 further stirrer 34 two side by side on the container part 30 eccentrically mounted rotary valves 50, 60 can serve with bulk material.
  • the rotary valves 50 and 60 are functionally similar to each other and with the rotary valve 5 insofar as the bulk material in each of the locks 50, 60 as well as in the lock 5 axially (that is parallel to the shaft 32) through an inlet port 53, 63 in a Ring chamber 56, 66 passes, from the respective cellular wheel in the locks 50, 60 within the annular chamber 56, 66 to an outlet opening 57, 67, which is offset relative to the associated inlet opening in the circumferential direction by about 180 °, and out of the annular chamber 56th , 66 axially in each case a discharge chute 59, 69 passes.
  • the locks 50, 60 are dimensioned in diameter as well as the lock 5, the locks under the container part 30 only in the region of their inlet ports 53, 63 and stand with its remaining portion with the outlet openings 57, 67 and the discharge chutes 59, 69 diametrically laterally beyond the outline of the container part.
  • each of the locks 50, 60 centrally each have a separate drive motor 42, 44 attached, which is coupled to the rotary drive of the respective cell wheel with the latter.
  • the container part 30 is closed off by its own lower bottom 36, which has two curved openings 32 opposite to the shaft 32 and convex to the shaft 32. These openings are the above-mentioned inlet openings 53, 63.
  • a stirrer 38 is rotatably connected, which is provided with six equally spaced wings and loosens the bulk material lying on the floor 36 and conveys into the inlet openings 53 and 63.
  • the locks 50, 60 have lids 54, 64 which are fixed under the floor 36 and have openings corresponding to the inlet openings 53, 63.
  • FIG. 6 shows an embodiment in which three cell wheel locks 70, 80, 90, equally spaced in the circumferential direction, are fastened under the bottom 46 of a container part 40, which are substantially identical to the aforementioned rotary valves 5, 50, 60.
  • the bottom 46 has three similar equally spaced, equal curved and the shaft 42 convex apertures as inlet ports 73, 83, 93 for the locks 70, 80, 90, in which a six-armed stirrer 48 in the container part 40 on the bottom 46 resting bulk material promotes.
  • the discharge chutes are located diametrically opposite the inlet openings.
  • Gate valve is described below only in connection with the rotary valve 50 in more detail. The structure to be explained applies in a corresponding adaptation for each of the above-explained rotary valves.
  • a disc-shaped gate valve 35 is parallel to the cover plate about a pin 62nd rotatable, which is arranged perpendicular to the cover plate 54 of the lock 50.
  • the gate valve 35 fills the gap substantially dust-tight and has one of the inlet opening 53 and a corresponding opening 58 in the cover plate 54 in size and arrangement the same passage 31.
  • FIGS. 7 and 8 the clearance for illustration is shown substantially larger than the cross section of the slider 35.
  • a radially projecting stem 37 is attached to the periphery of the slide, which stem projects outward through a peripheral slot in the sealing ring 55 extends and ends in a handle 39.
  • handle 37 and handle 39 are replaced by a coupling of the pin 62 to the drive motor 42 for the feeder of the lock 50 via a shaft 46 and a not shown switched on and off reduction gear or the like transfer member.
  • connection or disconnection is a rotational adjustment of the gate valve 35 in the sense of a closure, a partial opening or full opening of the inlet port 53 possible.
